WIRE GRIP.

Application filedv February 24, 1922. SeraINo. 538,83).v

Be it known that I; CASPER H. DIGKE, a

4citizen of Ythe United States,residin'g atV Downers Grove, in the county of Cook and tate of Illinois, have invented certain new," and useful improvements in `Wire Grips, of.

which the followingV is a. specification.

This invention relates to wire grips.. V

It is particularly adapted for use in-tlie running of telephone, telegraph and power system lines, although applicable for use in other fields. Such grips are ordinarily used to properly tension the wires between poles, etc. g

One of the objects of this invention is to provide an improved wire grip.

Another object is to provide an improved grip in which the wire gripping jaws may be latched in open or wire receiving position.

Another object is to provide a. grip in which the jaws may be frictionally locked in open position without manipulating any part of the tensioning tackle.

Another object is to provide a grip which is etlicient. reliable, simple and inexpensive.

Other objects and advantages will hereinafter appear.

Embodiinents of the invention are illustrated in the accompanying drawings, wherein Fig. l is a top plan of a grip.

Fig. 2 is a side elevation partly in section, showing the grip in open and closed positions.

Fig. 3 is an enlarged section through the latch for automatically holding the jaws in open position. f

The grip has a relatively fixed jaw l andV a relatively movable jaw 2. These two jaws may be separated to open or wire receiving position and may be moved together to closed or wire clamping position.

Jaws 1 and 2 are pivotally interconnected by a strap 3 and a lever 4. These pivotal connections cause the jaws to be maintained in a substantially parallel relation to increase the effective wire gripping surfaces.

J aw l is somewhat longer than jaw 2 and has a longitudinal closed slot 5 therethrough. A pin 6 lies in and is movable along slot 5. A pair of operating links 7 are connected at one end to pin 6 and at the other end to lever 4. A draftdevice 8, which ordinarily isy in the form of a loop for attachment to the tensioning tackle used to closed position wherein by linemen, is connected to pin 6 on `the outside of links 7 A spring 9, which is coiled about a lug lO, projecting from one of the links 7 has one end against a stop l1 on the saine link andl the V'other end against a shoulder 12 on lever 4. This spring yieldingly biases the .jaws pin 6 is toward the outer end of slot 5.

In "orderto open the jaws to receive theA w1re, pinv 6 1s moved toward the inner end of slot 5 against the Vtension of spring). The `toggle comprising links 7 and .lever 4 is thus closed and the .movable jaw is moved away from the fixed jaw as 'shown by the dotted lines of Fig. 2.

A hole 13 is made through jaw-1 so. as to 'lie behind links 7 when the jaws are open.

Into hole 13 a ball 14 isset, and loosely retained in position byslightly upsetting the rim of the hole on one or both sides. diameter .of ball 14 is somewhat greater than the distano@ between the facing surfaces of links 7. 1When the jaws are opened,

by forcing pin 6 to the inner end of slot 5,. links 7 are forced upon the ball and separated. The friction between the ballV and links 7 and between the `ends of the links and V`the ends of draft deviceSat pin 6, holds the jaws open against the force of spring 9. However, a slight pressure on lever 4 or a slight pull on draft device 8 overcomes the friction, Vthe jaws are released and spring 9 is free to close the same upon the wire.

Thus the jaws may be automatically locked in open position until thejwire is placed therebetween, whereupon by the simple operation of pressing the toggle or tightening upon the tackle will unlatch the jaws. The greater the pull upon draft device 8 ineen The y the tighter the wire will be clamped between the jaws. The jaws are locked open irrespective of the angular position of the draft device and tackle.

Having described my invention whatl claim as new and desire to secure by Letters Patent, is l j 1 l. A wire grip having a pair of relatively movable jaws for clamping a wire.

between them, a draft .deviceA for attach.- ment to tensioning" tackle and associated with the jaws to cause the same tc clamp the wire, and a ball for frictionally holding the jaws in non-clamping position.

2. A wire grip having a pair of relatively movable jaws adapted to be opened to' re- Y ceive a wirev and to beclosed to grip 'a wire,

movable jaws adapted to be [opened to re-y ceive a wire andato be closed to grip a wire between Ythe-in, a draft device, a leverV pivotally interconnecting the jaws, a. link interconnectinp,1 the lever andthe draft de vice, and a friction element independent of theY draft Vdevice associated with one of the I jaws and acting upon the link tok hold. the

jaws inv open position irrespective of the angnlar position of the draft device.

4e. A wire grip having a pair ofrelatively inovable jws adapted to be separated to receive a wire and to be Vbrought together to clanip a wire between-them, a lever pivotally interconnecting the jaws, a draft de vice, a link interconnecting the lever and the draft device, and a ball held by one of the jaws and acting upon the link to holdrthe jaws in open position.

'5. A wire grip comprising a relatively vfixed jaw with aslotA therein, a relatively movabler jaw pivotally connected to the fixed jaw, a lever interconnecting thejaws, af

drat't device, a. pin passing through the slot in the fixed j'a-w'and attaching the 'draft device thereto, a pairfof parallel links interconnecting the pin and the lever and acting to communicate nioveinentfroin the draft device to the .movable "jaw, Vand a ball held in theV iXed-jaw Iand over which the links niove when the jaws are in open position and cooperating` with the links to hold the jaws in ope-n position.
